In some embodiments, a sole layer can change thickness relative to the second sole layer.In different embodiments In, first layer 110 can be thicker than the second layer 120.For example, there is first layer 110 first thickness 140, the second layer 120 to have second Thickness 145.In some cases, first thickness 140 is more than second thickness 145 to help to provide additional delay for wearer Punching.

Embodiment may include the extension for promoting footwear sole construction during dynamic motion and/or the measure of adaptability.One In a little embodiments, footwear sole construction can be configured with auxetic measure.Specifically, one or more layers of footwear sole construction or component can Carry out auxetic movement (such as extension and/or contraction).Expand on the direction orthogonal with direction of pull and on the direction of pulling force The structure of exhibition is referred to as auxetic structure.In order to make reader more fully understand some disclosed embodiments, Fig. 2 and Fig. 3 are schematically Show how the geometry of hole 130 and surrounding first sole element 132 makes to form first layer 110 (referring to Fig. 1) A part for first auxetic materials 250 generates the auxetic behavior (" the first behavior ") of the first kind.Fig. 2 and Fig. 3 show when the When one auxetic materials 250 are in stretching in one direction, the two-way extension of a part for the first auxetic materials 250.Fig. 2 shows The parts of first auxetic materials 250 has original width 210 and initial length in initial (unstressed) state 200 220.Under its unstress state, the part of the first auxetic materials 250 has the hole 130 surrounded by the first sole element 132.Often First sole element 132 is engaged at its vertex 134, leaves multiple opening (" openings ") 234.Fig. 2 shows embodiment In, hole 130 is triangle star-shaped aperture, and the first sole element 132 is generally triangle character, and opening 234 indicates triangle star-shaped aperture 130 Inside.As best seen from, in one embodiment, being open 234 is characterized in when the first auxetic materials 250 in enlarged view Part when being not under pulling force, with relatively small acute angle.

Fig. 2 and Fig. 3 further provide the first auxetic materials 250 its non strain state 200 (being shown in Fig. 2) with First auxetic materials 250 (as shown in Figure 3) when being in stress state or resultant force state 204 under tension on its longitudinally The comparison of a part for embodiment.In figure 3, applying pulling force to the first auxetic materials 250 in the direction of the arrow makes neighbour Close the first sole element 132 rotation, which increase the relative spacings between the first adjacent sole element 132.For example, by scheming See in 2 and Fig. 3, the relative spacing (and the size in hole 130 therefore) between adjacent sole element 132 is with pulling force Apply and increases.Since the increase generation of relative spacing (is attributed to the geometric form of the original geometry form in hole in all directions Shape), this causes auxetic materials along direction of pull and along the Directional Extension orthogonal with direction of pull.For example, shown in Fig. 2 In embodiment, in original state 200, the first auxetic materials 250 have the initial length of (such as longitudinal direction) in one direction 220, and along the original width 210 of the second direction (such as horizontal direction) orthogonal with first direction.In stress state or Resultant force state 204 (referring to Fig. 3), the first auxetic materials 250 have the increased Len got 214, Yi Ji on direction of pull Increased gained width 212 on the direction orthogonal with draw direction.It is understood that the extension of the first auxetic materials 250 is not It is limited to the extension on direction of pull.

Therefore, in some embodiments, the footwear sole construction 104 of Fig. 1 can have auxetic layer, which may be used as interior Bottom or midsole presentation show the first auxetic behavior.In one embodiment, auxetic layer may be constructed the midsole in footwear sole construction, When article of footwear hits ground, which, which provides, buffers and absorbs impact force.

Although hole 130 is shown as the shape with 3 stars in fig. 1-3, generally, in various embodiments, more Each hole in a hole 130 can have any kind of geometry.In some embodiments, hole can have polygon several What shape, including convex and/or female polygonal geometry.In many cases, the geometry in hole can be characterized as having There is the polygon on the side for being directed toward inside.For example, in embodiment shown in fig. 1-3, the geometry in hole 130 can be characterized as With not be straight side triangle, this while while midpoint have be directed toward on the inside of vertex.By these direction insides The angle that vertex is formed is referred to as " recessed " angle.The re-entrant angle that apex on the inside of these directions is formed can be at 179 degree (when side is several When being straight) it arrives in the range of such as 120 degree or smaller.

Other geometries are also feasible, including various polygons and/or curved geometric.It can be with one or more The exemplary polygonal shape that hole 130 is used together includes but not limited to regular polygon (for example, triangle, rectangle, five Side shape, hexagon etc.) and irregular polygon shape or non-polygon shape.Other geometries can be described as four sides Shape, pentagon, hexagon, heptagon and octagon or other polygonal shapes with indented edge, or can even have Aduncate side.As described above, the sole element for limiting hole can be geometric properties, such as triangle character, quadrangle are special Sign, trapezoidal characteristics, hexagonal features, octagon feature, oval feature and circular feature.

Although embodiment shown in figure is shown as the hole with approximate polygon geometry, hole includes approximate dotted Vertex, side or edge are abutted in apex, but in other embodiments, some or all holes can be non-polygon.Specifically Ground, in some cases, the outer edge in some or all of holes or side can not be engaged in apex, but can be continuously curved It is bent.For example, hole can have there are three vertex, wherein three aduncate sides engage three vertex.Moreover, some embodiments can To include the hole with geometry, the geometry includes the straight edge connected via vertex and does not have any point or a top The bending of point or non-linearity edge.

In the embodiments illustrated in the figures, the auxetic structure for including interior bottom or midsole with auxetic layer can be in longitudinal side To or horizontal direction on stretch.However, the auxetic for including the geometry hole surrounded by geometry part discussed in this application The construction of structure provides can be along any first direction for applying pulling force and along the second party orthogonal with first direction To the structure of extension.Also, it is to be understood that propagation direction, i.e. first direction and second direction, it totally can be with auxetic knot The plane tangent of structure.Specifically, auxetic structure discussed here totally can be substantially not in the thickness phase with auxetic structure It is extended on the vertical direction of pass.

As described above, being referred to as auxetic knot in the direction orthogonal with direction of pull and the structure extended on direction of pull Structure.Fig. 4 and Fig. 5 schematically shows how the geometry of protrusion 150 and surrounding second sole element 142 make to be formed A part for second auxetic materials 450 of the second layer 120 (referring to Fig. 1) generates auxetic behavior (" the second row of Second Type For ").Fig. 4 and Fig. 5 shows one of the second auxetic materials 450 when the second auxetic materials 450 are in stretch in one direction Partial two-way extension.Fig. 4 shows the part of the second auxetic materials 450, and the part is in 400 times tools of initial (unstressed) state There are original width 410 and initial length 420.

Under its unstress state, the part of the second auxetic materials 450 has the protrusion surrounded by the second sole element 142 150.Each pair of second sole element 142 engages at its vertex 144, leaves multiple faces (" face ") 434.Implementation shown in Fig. 4 In example, protrusion 150 is triangle star protrusion, and the second sole element 142 is the feature of triangle, and face 434 indicates triangle star The side of protrusion 150.

The part that Fig. 4 and Fig. 5 further provides the embodiment of the second auxetic materials 450 is unstressed initial at its A part for state 400 (being shown in Fig. 4) and the identical embodiment of the second auxetic materials 450 is at which in the pulling force of longitudinally Under (as shown in figure 5, i.e. stress state or resultant force state 404) when comparison.In Figure 5, on the direction shown in arrow to Second auxetic materials 450, which apply pulling force, makes the second adjacent sole element 142 rotate, this expands the second auxetic materials 450 Size.Since the increase of size occurs in all directions (due to the shadow of the geometry in the original geometry form of protrusion Ring), this makes auxetic materials along draw direction and along the Directional Extension vertical with draw direction.For example, shown in Fig. 4 Embodiment in, in original state 400, the second auxetic materials 450 have the initial length of (such as longitudinal direction) in one direction Degree 420 and along the second direction (such as horizontal direction) orthogonal with first direction original width 410.In stress state or Under resultant force state 404 (referring to Fig. 5), the second auxetic materials 450 have the increased Len got 414 on direction of pull, and Increased gained width 412 on the direction orthogonal with draw direction.It is understood that in some embodiments, second The extension of auxetic materials 450 is not limited to the extension on direction of pull.

Therefore, in some embodiments, the footwear sole construction 104 of Fig. 1 can have auxetic layer, the auxetic layer to show second Auxetic behavior, may be used as outer bottom.In one embodiment, auxetic layer may include the outer bottom in footwear sole construction, work as footwear When article hits ground, which provides earth-grasping force and ground contact.In some embodiments, the second auxetic behavior can be with One auxetic behavior is different (referring to Fig. 2 and Fig. 3).In some other embodiments, the first auxetic behavior may be substantially similar to Second auxetic behavior.

In various embodiments, one or more of the second layer 120 protrusion 150 can also be generated by being exposed to various power Shape or geometry, size and/or height variation (referring to Fig. 1).For example, in Fig. 4, the first protrusion 408 has place In the vertex 412 of the first height 460.In some embodiments, height of the vertex 412 relative to the base portion 418 of the first protrusion 408 It is overall to be located in the perpendicular of the second auxetic materials 450 and prolong upwards from the second nearside 122 of the second auxetic materials 450 It stretches.

With reference to figure 5, in some embodiments, when power 506 is applied to the first protrusion 408, the height of the first protrusion 408 can To change.In Figure 5, the height on the vertex 412 of the first protrusion 408 is reduced to the second height 560.In the embodiment of Fig. 4 and Fig. 5 In, the second height 560 is less than the first height 460.

In other embodiments, when different power is applied to footwear sole construction, the second height 560 may be substantially similar to Or more than the first height 460.The variation of the size and Orientation of power depending on application, area or shape can be different.At some In embodiment, different power can allow the extension of protrusion.In some cases, this extension occurs in the horizontal direction.Example Such as, in one embodiment, the second layer can be exposed to the compressing force on the direction parallel with horizontal plane, be more than the to generate Second height 560 of one height 460.

Therefore, in various embodiments, the second auxetic materials 450 can be subjected to different types of power.During dress, Foot and ground force can compress the second layer along total vertical direction.In some embodiments, the second layer can extend or through stress, So that the geometry of protrusion 150 is flared out.This can occur during vertical compression, for example, when wearer by he or she Weight when being applied on article.Level tensioning or pulling force can also contribute to the extension of the component of ground-engaging.For example, when prominent It rises when being subjected to the horizontal pull caused by the friction with ground, protrusion can be on direction of pull and vertical with pulling force Side extend up.Therefore, the auxetic characteristic of the second auxetic materials 450 allows the extension of the various levels of the second layer, to Increase its size in a horizontal plane.

In the embodiments illustrated in the figures, the auxetic structure for including the outer bottom with auxetic layer can be in longitudinal direction or cross It is pulled up to side.However, the auxetic structure that the geometry protrusion for being surrounded by geometry part discussed in this application forms Construction provide and can expand along any first direction for applying pulling force and along the second direction orthogonal with first direction The structure of exhibition.Also, it is to be understood that propagation direction, i.e. first direction and second direction, it totally can be with auxetic structure Plane tangent.Specifically, auxetic structure discussed here totally can be substantially relevant not perpendicular with the thickness of auxetic structure Histogram extends up.

The additional information of various actions about auxetic structure can obtain in following patent：What on June 9th, 2016 announced U.S. Patent Publication No. be 2016/0157553 (previously on December 9th, 2014 U.S. Patent Application No. submitted be 14/564, 694) patent of entitled " shoes with flexible auxetic ground engagement component ", the U.S. Patent Publication that on June 9th, 2016 announces Number being 2016/0157558, (previously on December 9th, 2014 U.S. Patent Application No. submitted be 14/565,143) is entitled The patent of " shoes with auxetic ground engagement component ", U.S. Patent Publication No. disclosed in 9 days June in 2016 are 2016/ 0157557 (previously on December 9th, 2014 U.S. Patent Application No. submitted be 14/564,797) is entitled " to have flexible draw The patent of the shoes of swollen footwear sole construction ", the U.S. Patent Publication No. that September in 2015 is announced on the 3rd be 2015/0245683 (previously in On March 10th, 2015, the U.S. Patent Application No. submitted was 14/643,254) entitled " with respective inner or outer liner The U.S. Patent Publication No. that the patent of auxetic sole " and on March 19th, 2015 announce be 2015/0075033 (previously in The U.S. Patent Application No. submitted on the 18th of September in 2013 is 14/030,002) entitled " auxetic structure and with band auxetic knot The shoes of the sole of structure ", the full content each applied are incorporated herein by reference.

As described above, in some embodiments, hole can receive the overwhelming majority of protrusion in hole.In some embodiments In, when the bottom of first layer or distal surface are disposed adjacent to top or the proximal face of the second layer, the second layer it is multiple prominent Each protrusion in rising may be configured to upwardly extend and enter in the corresponding aperture in multiple holes.Fig. 6 is describe the second layer 120 one Point the second protrusion 610 corresponding second hole 620 how entered in the part of first layer 110 and the schematic diagram being received. As shown in the enlarged view of Fig. 7, the plane of basic horizontal of second protrusion 610 in the entire height of the second protrusion 610 In have substantially 3 points of star-shaped cross-sectional shapes.Second protrusion 610 can also be characterized as having along edge (for example, first Edge 612 between part 613 and second part 614, as shown in Figure 7) engagement three pyramid part (first parts 613, second part 614, Part III 615, as shown in Figure 7).The peak of all three pyramid parts forms the second protrusion 610 vertex 650.As seen in Figure 7, each pyramid part of the second protrusion 610 or " arm " further include two " faces ". For example, it can be seen that first part 613 has the first face 621 and the second face 622, they are engaged along top edge 623.

Back to larger view shown in Fig. 6, in some embodiments, each protrusion of the second layer 120 can be with Corresponding aperture in one layer 110 is related.Specifically, as shown in Figure 7, first layer 110 includes for receiving the second protrusion 610 Two holes 620.For reference purposes, there is the outside corresponding to each protrusion (such as to face out for each protrusion of protrusion 150 Side or face) outer surface.Moreover, there is inner surface, the inner surface to correspond to the inside in each hole (that is, prolonging in each hole in hole 130 The surface of first thickness 140 is extended through, as shown in Figure 6).For the purpose of this disclosure, term " assembly ", " in conjunction with " or " cooperation " Use should be understood refer to protrusion access aperture concept.Relationship between two parts is not needed close, close or is fixed, So that protrusion is described as assembling in corresponding hole or is adapted with corresponding hole.Therefore, in one embodiment, when prominent It rises after inserting in the hole and being received by hole, the outer surface of protrusion is remained substantially or entirely to be separated with the inner surface of corresponding aperture When, protrusion is assembled in hole.In other words, the outer surface of protrusion need not physically contact with any region of the inner surface in hole, So that two parts are assembled or are combined together.The combination will be further discussed about Fig. 8.

In various embodiments, the size and shape of each protrusion of protrusion 150 can be designed as in different implementation It is assembled in corresponding hole in example.For example, with reference to figure 7, the second protrusion 610 has outer surface 616, and outer surface 616 is defined or limited Fixed first volume.In addition, the second hole 620 is defined by the inner surface 626 in the first thickness 140 of the second layer 120 (referring to Fig. 6), Inner surface 626 defines or is limited to the second volume (shown in dotted line in the figure 7) extended between distal end 624 and proximal end 625.The One volume appears larger than the second volume.In one embodiment, the first volume is substantially greater than the second volume, at least in shoes Bottom structure makes the outer surface 616 of the second protrusion 610 remain the inner surface with the second hole 620 when being in unstressed or original state 626 separate.Therefore, in some embodiments, the second hole 620 and the second protrusion 610 may be configured to applying drawing to footwear sole construction It independently extends and/or shrinks when power.In other words, referring to Fig. 6, in some embodiments, the first auxetic row of first layer 110 The second auxetic behavior to can be structured as independently of the second layer 120 occurs.Therefore, in one embodiment, first layer 110 It is joined to the second layer 120, but its auxetic performance is not necessarily combined with the auxetic performance of the second layer 120, similar or interaction.

In addition, the outer surface 616 of the second protrusion 610 can have it is substantially similar to the profile of the inner surface 626 in the second hole 620 The geometry of (or be adapted), so as to the two part general alignments or correspond to each other, as shown in Figure 7.However, in other realities Apply in example, the geometry of the second protrusion 610 can be different from the geometry in the second hole 620 so that two layers with substantially Different auxetic behaviors is related.In some cases, this shape difference can prevent protrusion from being received by hole, but in other implementations In example, protrusion can remain small enough to be received by corresponding hole.In addition, in some embodiments, it can be by relative to prominent It acts the shape for changing hole and the first auxetic behavior of first layer 110 is configured to the second auxetic behavior independence with the second layer 120 Ground occurs.

In addition, in other embodiments, can change with the relevant orientation of each form of auxetic structure, so that two layers It is related to substantially different auxetic behavior.For example, first layer 110 may include the hole 130 of the first form, the second layer 120 can With the protrusion 150 including the second form.In some embodiments, the hole 130 of the first form can be arranged along first direction, second The protrusion 150 of form can be arranged along the second orientation different from first orientation.In some cases, this misalignment can be with Prevent protrusion from being received by hole, but in other embodiments, protrusion can keep sufficiently small or close alignment corresponding to being enough Hole receive.In some embodiments, the first auxetic behavior of first layer 110 can be with any of through hole or protrusion or two The variation of a orientation and the second auxetic behavior for being configured to the second layer 120 independently occur.

As described above, in various embodiments, the size of each hole 130 and each protrusion 150 can change.At some In embodiment, hole 130 can be blind hole, wherein the only one end (that is, distal end) in each hole is open or exposure, and each hole Opposite end (that is, proximal end) remain and be enclosed in the thickness of layer.In other words, in this case, only porose one end can To be exposed along the outer surface of layer.In other embodiments, hole 130 can be through-hole, and one end of mesoporous is along the first of layer Outer surface is open or exposed, and the opposite end of same holes is open or exposed (referring to figure also along the opposing outer face of this layer 12).In other words, through-hole extends through the whole thickness of layer.In addition, in some other embodiments, layer can utilize through-hole With the combination of blind hole.When through-hole extends through the thickness of sole layer (referring to Figure 11), through-hole can be modified or not be advised Width or width then can be substantially homogeneous (referring to Figure 12) in the whole thickness of sole layer.

In some embodiments, when combining between the two layers, the first side of a layer can be with another layer The second side flushes.In one embodiment as shown in fig. 8, the part in the first distal side 114 of first layer 110 could be provided as with The part of second nearside 122 of the second layer 120 flushes or is arranged against the part, so that the part physical contact with one another per side. In some embodiments, basic entire first distal side 114 of first layer 110 can be with the portion of the second nearside 122 of the second layer 120 Divide and flushes.Example is described in the viewgraph of cross-section 830 of the first footwear sole construction 800, a wherein part for first layer 110 is shown Go out for be arranged above a part for the second layer 120 and with the part direct neighbor.In addition, it could be seen that the first hole 852 connects The first protrusion 862 is received, the second hole 854 has received the second protrusion 864, and third hole 856 has received third protrusion 866, the 4th hole 858 have received the 4th protrusion 868.Moreover, the first upper surface 872 of first layer 110 can contact the first following table of the second layer 120 Second upper surface 874 in face 882, first layer 110 can contact the second lower surface 884 of the second layer 120, and first layer 110 Third upper surface 876 can contact the third lower surface 886 of the second layer 120.It should be understood, however, that flush configuration is not The uninterrupted or continuous physics between the first distal side 114 of first layer 110 and the second nearside 122 of the second layer 120 is needed to connect It touches.It in some embodiments, can be by protrusion 150 substantially completely or whole be inserted into corresponding hole 130 " flushes structure to realize Make ", as shown in cross-sectional view 830, and the first distal side 114 and two surfaces of the second nearside 122 are not completely each other It is pressed against.Moreover, for the purpose of this disclosure, in the embodiment that first layer 110 and the second layer 120 flush each other, each protrusion Height be always less than corresponding hole, allow the smooth interconnection between first layer 110 and the second layer 120.

In fig. 9 it is shown that the cross-sectional view of the embodiment of a part for the second footwear sole construction 900.With hole first Layer 902 and the second layer 904 with protrusion are set as located adjacent one another and substantially flush each other.Second footwear sole construction 900 wraps It includes and receives the 5th hole 910 of the 5th protrusion 912, the 6th hole 920 for receiving the 6th protrusion 922, receives the 7th of the 7th protrusion 932 Hole 930 and the octal 940 for receiving the 8th protrusion 942.As described above, in some embodiments, each size in hole 130 It can change.For example, hole can be with modified respective depth, wherein each depth can be understood as prolonging from the proximal end 952 in hole Reach distal end 954.In the embodiment in fig. 9, there is the first depth 911, the 6th hole 920 to have the second depth in the 5th hole 910 921, there is seven apertures in the human head 930 third depth 931, octal 940 to have the 4th depth 941.And the first depth 911 and the second depth 921 is substantially similar, and the 4th depth 941 is more than the first depth 911 or the second depth 921.Moreover, third depth 931 is more than first Each in depth 911, the second depth 921 and the 4th depth 941.Further, it can be seen that the 5th hole 910,920 and of the 6th hole Octal 940 is individually blind hole, and seven apertures in the human head 930 is through-hole and extends through the thickness 917 of first layer 110.In each case Under, the depth in four holes is substantially greater than the height of the chamber or the complementary protuberance in channel that are inserted into hole.

Moreover, in fig. 9, it can be seen that, in some embodiments, the other sizes of the second footwear sole construction 900 can become Change.For example, there is the first width 992, the 6th protrusion 922 to have than 992 smaller second width of the first width in the 6th hole 920 993.Similarly, there is octal 940 third width 998, the 8th protrusion 942 to have wider than the first width 992 the smaller 4th Degree 999.In some embodiments, the width in a hole can be substantially greater than the width in another hole.As shown in figure 9, the 6th First width 992 in hole 920 is more than the third width 998 of octal 940.However, in fig.9, the second of the 6th protrusion 922 is wide Degree 993 is substantially similar to the 4th width 999 of the 8th protrusion 942.

In fig. 10 it is shown that the cross-sectional view of the embodiment of a part for third footwear sole construction 1000.With hole One layer 1002 and the second layer 1004 with protrusion are set as located adjacent one another and substantially flush each other.Third footwear sole construction 1000 include the 9th hole 1010 for receiving the 9th protrusion 1012, the tenth hole 1020 for receiving the tenth protrusion 1022, reception the 11st The 11-holes 1030 of protrusion 1032 and the 12nd hole 1040 for receiving the 12nd protrusion 1042.As described above, in some realities It applies in example, each size of protrusion can change.For example, protrusion can be with modified corresponding height, wherein each height can To be understood to that the base portion 1052 from protrusion extends to vertex 1054.In the embodiment in figure 10, the 9th protrusion 1012 has the One height 1013, the tenth protrusion 1022 have second height the 1023, the 11st protrusion 1032 have third height 1033, the 12nd Protrusion 1042 has the 4th height 1043.And the second height 1023 and third height 1033 are substantially similar, it can be seen that first is high Degree 1013 is more than the second height 1023 or third height 1033.Moreover, the 4th height 1043 is high more than the first height 1013, second Degree 1023 and third height 1033 in each.In addition, in each case, the depth in four holes, which is substantially greater than, is inserted into hole Chamber or the complementary protuberance 150 in channel height.

It in some embodiments, can be big with 110 relevant degree of expansion of first layer caused by the pulling force in Figure 15 In the degree of expansion of the second layer 120.In other embodiments, relevant with first layer 110 caused by the pulling force in Figure 15 Degree of expansion can be less than the degree of expansion of the second layer 120.Moreover, in some embodiments, produced by the pulling force in Figure 15 Can be more than with a relevant degree of expansion in specific region of first layer 110 it is relevant with the same area of the second layer 120 Degree of expansion.It in other embodiments, can be with base with 110 relevant degree of expansion of first layer caused by the pulling force in Figure 15 This is similar to the degree of expansion of the second layer 120.

It in various embodiments, can be with 110 relevant shrinkage degree of first layer caused by the pulling force in Figure 15 More than the shrinkage degree of the second layer 120.In other embodiments, related to first layer 110 caused by the pulling force in Figure 15 Shrinkage degree can be less than the second layer 120 shrinkage degree.Moreover, in some embodiments, being produced by the pulling force in Figure 15 It is raw can be more than to a relevant shrinkage degree in specific region of first layer 110 it is related with the same area of the second layer 120 Shrinkage degree.It in other embodiments, can be with 110 relevant shrinkage degree of first layer caused by the pulling force in Figure 15 It is substantially similar to the shrinkage degree of the second layer 120.

In addition, in some embodiments, auxetic response (such as extension or contraction) can occur over just in first layer 110, Without in the second layer 120.In another embodiment, auxetic response (such as extension or contraction) can occur over just second In layer 120, without in first layer 110.

Therefore, in some embodiments, footwear sole construction 104 may include the sole system for the multilayer for providing different auxetic responses System.When first layer 110 shows the first auxetic behavior, the second layer 120 can in a manner of unrelated with the first auxetic behavior table It is existing, and with the second different auxetic behavior responses.Auxetic sole system can provide not in terms of buffering and support for wearer With the covering of degree.In some embodiments, footwear sole construction 104 provides to user and allows to move into Mobile state the various of foot The system of response.In one embodiment, the bending of each in first layer 110 and the second layer 120 and extension can respond It is distributed and occurs in the different and dynamic pressure generated by wearer's use.

Figure 16 provides the diagram of the footwear sole construction 104 in the article 100 of assembling.As shown in Figure 16, the second layer 120 provide the outermost layer in article 100.Therefore, in some embodiments, the second layer 120 may be constructed such that article of footwear Outer bottom.Can with it is further seen that, in some embodiments, the outer surface 1650 of the second layer 120 may include in apparent surface The corresponding recessed area 1600 (for example, hollow region, recess portion etc.) of protrusion of upper formation, as discussed previously herein.Moreover, In some other embodiments, article 100 and footwear sole construction 104 may include in " auxetic structure and with auxetic structure Auxetic form, structure, feature and/or behavior described in the footwear of sole " application.
